WINDOW.

Specification of Letters'latent.

Patented June 2, 1914.

Application filed. February 14, 1914. Serial N 0. 818,657.

To all whom it may concern:

Be it known that I, JAMES M. Jones, a

citizen of the Dominion of Canada, and subject of the King of Great Britain, residf ing at Hamilton, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Windows, of which .the following is a specification.

This invention relates to an automatic weather strip for window sashes and is particularly applicable to the type of window sash commonly known as horizontally pivoted. It is highly desirable to so mount the window sash upon a supplemental sliding stile that they may be swung thereupon for the purpose of swinging the outside of the window into position so that it may be cleaned from the inside of the room in which it is located thereby rendering it unnecessary for the window cleaners to stand out upon the window sill. It is also desirable to provide a weather strip so that the window may be weather tight under normal conditions. In some constructions heretofore employed these weather strips are utilized as the locking element to prevent the horizontal swinging of the sash with relation to the supplemental stile, which is the case in the present construction. However it has been found that in some cases the window washers fail to move the weather strips into locking position after the windows have been washed and the windows are left unlocked. That is, they are left in such position that there is nothing to prevent them from swinging horizontally upon their pivots at the slightest touch. Serious accidents have occurred by reason of the fact that persons have leaned against these unlocked windows and have fallen out of the windows and been killed.

It is a. particular object of the present invention to provide improved means actuated by the vertical movement of the window sash which will serve to automatically shift the strip into such locking position as the window sash is lowered.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing, Figure 1 is a sectional perspective view of a window constructed in accordance with the invention. Fig. 2 is a horizontal sectional View detailed perspective view of the automatic weather strip hereinafter described. 7

Like numerals designate corresponding parts in all of the figures of the (slrawing.

lVhile I have shown the weather strip as applied to one side only of a sash, it is ap parent that it may :be as readily applied .to both sides of the sash and to both the upper and lower sash.

Referring to the drawing the numeral 5 designates the window frame; 6 designates the parting strip between the upper and the lower sash; 7 designates the lower sash which is pivoted for horizontal swinging movement-to a supplemental stile '8 by means 01 .131 pivot indicated at 9.

The inside weather strip is indicated at 10 and between this fixed weather strip 10 and the supplemental stile, the weather strip proper is located. As best illustrated in Fig. 3 this weather strip comprises the spaced plates 11 and 12, the plate 12 preferably being slightly wider than plate 11. These plates are spaced from each other by pins 13 and lie upon opposite sides of a fixed strip or bar 1 1 which is cut out at 15 to accommodate the pins 18. The plate 12 is pivotally connected by a screw 16 with a finger 17, said finger 17 in turn being connected by a screw 18 with an eyelet 19, said eyelet being screwed into the window frame at 20.

The operation of the device is as follows: lVit-h the parts in the positions shown in Figs. 1 and 2 the Weather strip is in its retracted position, in other words the edge of plate 12 is withdrawn from the vertical groove 21 formed in the edge of the sash. At this time the window sash is free to swing upon its pivot 9. It is understood that the weather strip is moved into such retracted position manually and when it is moved into such retracted position by an upward and rearward swinging movement on the pivots formed by the screws 16 and 18, 17 is thrown outwardly to the horizontal position shown in Fig. 1 and there lies in the path of movement of the window sash so that as the window sash is lowered, the finger 17 is swung downwardly until it lies in a vertical position and when it is thus swung downwardly from screw 18 which is pivoted upon eyelet 19, it consequently swings the weather strip down- I through one side thereof, and Fig. 3 is a wardly and outwardly to bring the edge of the plate 12 into the vertical groove 21 in a manner that will be readily understood.

While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

.Having described my invention, what I claim is:

1. In a window construction the combination with a vertically slidable sash, pivoted for horizontal swinging movement, of a weather strip movable into and out of engagement with said sash, a member arranged to be moved into the path of movement of said sash by the movement of said weather strip out oi engagement with said sash, the engagement of said sash with said member when the sash is closed serving to move said weather strip into engagement with said sash.

2. A window construction comprising a slidably mounted sash, said sash being pivoted to swing horizontally and provided with a vertical groove along its outer edge,

a weather strip arranged to be moved into and out of said groove, pivoted to said weather strip and pivoted to a fixed element carried by the window frame, the arrangement of said member being such that the movement of the weather strip from said groove swings said member into the path of movement of the window sash, the engagement of said window sash with said member serving to force said weather strip into engagement with said groove.

3. In a window construction the combination with a vertically slidable window sash pivoted horizontally for swinging movement and having a vertical groove formed in its outer face, of a weather strip comprisin a pair of spaced plates a fixed bearing member carried by the window frame, a finger pivoted to said bearing member and to said weather strip in such manner that movement of the weather strip out of said groove throws said finger into the path of movement of the window sash substantially as shown and described.

In testimony whereof I atlix my signature in presence of two witnesses.

JAMES M. JONES.
